Week 8 – Large Language Models & AI Applications

This week focused on Large Language Models (LLMs), which are one of the most advanced forms of artificial intelligence today. These models, like ChatGPT, are designed to understand and generate human-like text using a transformer-based architecture. I learned that LLMs go through two major stages: pre-training on massive datasets and fine-tuning for specific tasks. This process allows them to perform a wide range of functions, from answering questions to generating content. In Google Colab, I explored how to use a transformer model to summarize large pieces of text. This exercise showed me how AI can quickly take complex information and turn it into something concise and useful. It made me think about how businesses could use this for things like reports, marketing content, customer service, and even social media management. Seeing this in action helped me understand why LLMs are becoming such an important tool across industries. This week really tied everything together from the course. It showed how machine learning, deep learning, and NLP all connect to create powerful tools like ChatGPT. As someone in marketing, I can see huge potential in using LLMs for content creation, automation, and audience engagement. At the same time, I also learned about challenges like bias, data quality, and ethical concerns, which are important to consider when using AI. Overall, this course has completely changed how I view AI—it’s no longer just technology, but a skill I can use to create real opportunities.
